Vanishing quantum confinement enables bright and thermally excited multi-carrier emission from semiconductor nanocrystals
Tjom Arens, Sander J. W. Vonk, A. Willem Vlasblom +5
Recently, nanocrystals in the regime of vanishing quantum confinement-termed bulk nanocrystals (BNCs)-have demonstrated remarkable optical gain characteristics. While their high-po…
Hot-carrier trapping preserves high quantum yields but limits optical gain in InP-based quantum dots
Sander J. W. Vonk, P. Tim Prins, Tong Wang +10
Indium phosphide is the leading material for commercial applications of colloidal quantum dots. To date, however, the community has failed to achieve successful operation under str…
Single-mode emission by phase-delayed coupling between nano-lasers
T. V. Raziman, Anna Fischer, Riccardo Nori +10
Near-field coupling between nanolasers enables collective high-power lasing but leads to complex spectral reshaping and multimode operation, limiting the emission brightness, spati…
Mode visualisation and control of complex lasers using neural networks
Wai Kit Ng, T. V. Raziman, Dhruv Saxena +7
Understanding the behaviour of complex laser systems is an outstanding challenge, especially in the presence of nonlinear interactions between modes. Hidden features, such as the g…
A silicon photonics waveguide-coupled colloidal quantum dot photodiode sensitive beyond 1.6 um
Chao Pang, Yu-Hao Deng, Ezat Kheradmand +6
Silicon photonics faces a persistent challenge in extending photodetection capabilities beyond the 1.6 um wavelength range, primarily due to the lack of appropriate epitaxial mater…
